AUTOMOBILE-LOCK.

Specification of Letters Patent. Patented No 30 1920 Application filed October 28, 1919, Serial No. 334,065. Renewed September 30, 1920. Serial No. 413,897. 7

To all whom it may concern:

Be it known that 1, JOHN A. OLBON, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Automobile-Locks, of which the following is a specification.

This invention relates to automobile locks.

An important object of the inventionis to in the steering post is shifted by the steering wheel throughinedium of a planetary gear train similar to that now in use upon Ford automobiles.

AfurtherobjeCt of the device isto pro vide a lock wherein the bolt when withdrawn by the key is automatically locked in with drawn position and wherein when it is desired to lock the steering post,. the use of the key is not necessary, but simplyfthe shifting of the latch which holds "the bolt in withdrawn position. 'This latter feature of the lock' eliminates to'a great extent liability of the owner of the machineleaving the key in the look after looking the same, and the feature of locking the bolt in withdrawn positi0n prevents accidental locking' of the steering post during travel of the machine.

Other objects and advantageswillbe apparentthroughout the course of'the following description. V

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my device and wherein like numerals designate like parts throughout, 1

Figure 1 is a perspective view'of the interior of aFord automobile showing my lock in 'osition upon the steering gear thereof.

1 ig.*2is a perspective of the lock taken from the opposite, side and somewhat enso 7 o'fFig. 6.

"Q'Fig. 3 is larged. p

I abottom plan view" showing the boltin'thewithdrawn or inoperative posi- I Fig. 4,is a view similar to that shown in 3, the bolt being in the locking positlon.

. F 5' a'section taken on the line 5-5 6 is of Fig. 5.

p g 7 is a detached perspective of the re.

a sectiontaken on the line 6-6 casing 14 provided upon its upper end with horizontal flange 15, the upper surface of which is adapted to slid'ably receive the horizontal flange 11 of the steering post 10. 'The horizontal flange of the'casing 14 is proyided with a vertical annular flange 15', hav 111g screw threads 16 formed upon the exterior thereof. The interior of the flange 15' is provided with an internal gear 17 formed integrally with the flange.

The upper end of the steering post 10 is provided with a vertically central bore 18 adapted to receive the reduced lower end 19 of a stub shaft 20 to the upper end of which is secured the steering wheel. The lower end of the stub shaft 20 is provided exter nally with gear teeth 21, which mesh with the pinions. 13. As these pinions also mesh with the internal gear 17 it will be seen that rotation of the stub shaft 20 through roedium of the steering wheel transmits a re-" duced rotation to the steering post 10.

A casing 22 is provided having an upstanding portion 23 provided with central bore 24 adapted to rotatably receive the stub shaft 20. This casing is provided with depending flange-25, having internal screw threads 16 adapted to receive external screw threads arranged on the annular flange 15. The casing 22 is providedwith. a horizontally extending ortion 26 having formed therein a recess 2 opening through the bottom of the extension. A plate 28 is provided to close the opening of the recess 27 having upstanding lugs 29 formed upon its upper surface.

These lugs are provided with alined openings 30. .A longitudinal rib 31 is provided upon the upper surface of the plate 28 and this rib is parallel to the center line of the openings Thehorizontal extension 261 is provided with an opening 32 in the rear wall 33 thereof. An opening 34 is also provided in casing 26, alined with the opening 32. The openings 30, 32, and 34.- co-act to receive a p n 35,

which holds the plate 28 in position in the bottom of the recess 27.

The horizontal portion :26 is provided with bore 36 adapted to slidably receive a locking bolt 37. The forward end of the lockingbolt 38 extends into a bore 39 formed in the annular flange 15'. This here extends through the internal 17. lit will be obvious that the bolt re'..-ei\"ing aperture destroys a portion of the teeth of the internal gear 17. The forward end 38 of the bolt 37 is accordingly provide l'with a gear tooth 38. to replace the tooth destroyed by the formation of thebore.

The rear. wall 33 of the extension 26 is provided with aperture 39 alined with the bore 36,wh1ch 1S adapted to recelve the rear end of the bolt'37 when in the withdrawn position. Pivoted toihe rear wall 3321s at l0 is a latch 41. spring 42 is provided having one end secured to the horizontal extension 7 .26 in. any suitablemanner and the other end engaging the latch 41 and forcing it into 'engagementwitha stop pin 43. This latch normally covers a portion. of the opening 39. The rear end of the bolt 37 is provided with a cam race 44 adapted to engage the latch and shiftit; to allow passage'of the boltthrough the opening and the bolt is provided "adj acent such end with annular groover'l5, adpted to receive the latch when the bolt arrives at the extreme rearmost position. I

The. bolt 37 is provided with transverse pin 4-6. A compression spring 4-7 surrounds the bolt 37 and extends intermediate the transverse pin 46 and the end wall 33 ofi'he extension 26 normally projecting the 'bolt for engagement withthe gear teeth 21 oi the stub shaft 20, as shown in Fig. 4. The lower end 48 ,of the transverse pin has its extremity arranged between the rib- 31 and pin Itwill be'seen that the rib 31-aud pin 35 .co-act to hold the tooth 38' of the bolt;

in the proper alinement. Mounted inthe extension .26 is a lock member t9,,having a rotatable key operated portion 50. Secured to the inner end of the rotatable key operated portion is a finger 51, adapted to engage the pin 46 and force the bolt rearwardly into the inoperative position.

.By inspection of Figs. 3, '5, and 6, itwill be obvious that the tooth 38 of thebolt 37, when the bolt is in withdrawn position, acts as a portion of the internal gear 17 and that, when in the locking position, the tooth 387 engages the external gear teeth 21 of the stubshait 20, looking the stub shaft and. steering wheel, allowing no play of the wheel.
